Human protein and coding gene
Syntaxin-7 is a protein that in humans is encoded by the STX7 gene .[ 5] [ 6]
In melanocytic cells STX7 gene expression may be regulated by MITF .[ 7]
STX7 has been shown to interact with STX8 ,[ 8] VPS18 ,[ 9] Vesicle-associated membrane protein 8 [ 8] [ 10] VPS11 .[ 9]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
